DEMI Moore was “barely conscious” and “convulsing” as her friends made a desperate 911 call.

Ten minutes of dramatic audio from the phone conversation were released in America last night.

It came hours after Demi’s estranged actor husband Ashton Kutcher, 33, flew back from Brazil to Los Angeles.

His return sparked suggestions that he would come to the Hollywood star’s rescue.

Demi’s life has spiralled out of control at the same time as Ashton has been pictured partying with several younger women.

After the 911 call on Monday, Demi’s spokesman said the actress was seeking professional help to treat her exhaustion and improve her health.

In the phone recording, Demi’s friends admit she “smoked something” and has been “having issues”.

One asks the operator: “Sir, this is an emergency. We need an ambulance here as soon as possible, please.

“She smoked something. It is not marijuana.

“It is similar to incense and she seems to be having convulsions.”

The female friend of 49-year-old Demi also says she is semi-conscious but, asked what she took, another friend says: “I didn’t really see.

“She has been having some issues so I’m not sure what she is taking.”

At one point, a voice, thought to be Demi, can be heard saying: “I won’t do it. I need an ambulance. I can’t go in there.”

Her friend also puts water on her back, complaining that Demi is “burning up” and not breathing regularly.

The operator advises Demi’s friends not to let her eat or drink anything. The Los Angeles attorney’s office recommended that certain portions of the call, thought to be drug references, were deleted to comply with federal privacy laws.

There are several long bleeps but the rest of the call was made public.

Earlier in the week, it was claimed Demi had collapsed after taking nitrous oxide, or laughing gas, at her Los Angeles home.

According to one report, she fell over after having a bad reaction. A source said Demi had symptoms of a seizure after ingesting large amounts of the substance.

People Magazine claimed her battle with prescription drugs was among the reasons her marriage to Ashton collapsed.

She filed for divorce after six years of marriage last November when Two and a Half Men star Ashton was accused of cheating on her with Sarah Leal, 23.
